IIUGI-I ERVIN, OF CHICAGO, ILLINOIS.

WASHING COMPOUND.

SPECIFICATION forming part of Letters Patent No. 448,421, dated March 1'7, 1891.

Application filed July 14.1890.

To all whom it may concern:

Be it known that I, HUGH ERVIN, of Chicago, in-thc county of Cook and State of Illinois, have invented a new, useful, and Improved IVashin g Compound, of which the fol; lowing is a full, clear, and exact description, such as may enable others skilled in the art to practice the same.

The object of my invention is to provide a simple and efficient washing compound which may be in a liquid form and may serve as a menstruuln or solvent for supplementing the detergent action of an ordinary soap, as well as to obviate the necessity for the usual excessive rubbing, while it may prove harmless to the most delicate fabric.

To these ends my invention consistsin the combination of ingredients hereinafter enumerated in about the proportions specified.

To sixty-four ounces of the oil of camphor, twelve ounces of the oil of sassafras, and six ounces of the oil of mirbane, thorouglny mixed, add ton gallons of the best quality of refined kersosene or hydrocarbon oil, preferably having a fire-test of 150 Fahrenheit, and when well digested place in packages of a size adapted to the use intended.

In order to obtain the best results for ordinary domestic purposes, I prefer to employ in the wash-boiler about one-half of a tablespoonful of the compound to each averagesi/led pail of water.

My improved compound readily dissolves all oily matter and loosens the dirt from the Serial No. 858,710. (No specimens.)

fabric to be washed, so that it requires but slight, if any, rubbing to become thoroughly cleansed. In most cases a mere rinsing is all that is required.

I am aware that hydrocarbon oil has been heretofore employed as a solvent in connection with soap; but the objection to its use in this way is that it leaves its odor in the clothes after washing, while it tends to discolor white fabrics and render them yellow. These objection-s do not pertain to my improved compound, the use of which renders the clothes odorless and perfectly whiteand clean.

I do not confine myself to the exact proportions specified, as they may be varied without departing from my invention; but those mentioned are preferred as having given the most satisfactory results in actual practice.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is.

A washing compound consisting of a mixture of the oils of camphor, Sassafras, and mirbane, and a refined hydrocarbon oil, in about the proportions substantially as specified.

In testimony whereof I have signed this specification,in the presence of two subscribing witnesses, this th day of July, 1890.
